Description
TECHNICAL FIELD
[0001] The present invention relates to method and system for
providing a personalized menu page on the wireless Internet by
using a mobile communication terminal. More particularly, the
present invention relates to method and system for providing a
personalized menu page, wherein the personalized menu page, in case
that a user gets access to the wireless Internet by using a mobile
communication terminal, has enhanced accessibility to a menu which
the user has used most frequently at the relevant location during
the relevant time, by grasping time information and the user's
location information.
BACKGROUND ART
[0002] Recently, mobile communication terminals such as cellular
phones, PCSs, PDAs, smart phones, handsets, web TVs and the like
are useful in carrying and getting access to the wireless Internet
at the same time, so as to obtain variety of information as a type
of characters or images. Moreover, since the CDMA-2000 network or
the IMT-2000 network is commercialized and delivered, the latest
wireless internet service also provides multimedia information such
as moving pictures, besides information formed of characters or
images.
[0003] Most of current data services provided by mobile
communication enablers and contents providers (CP) are performed
through the wireless Internet based on wireless application
protocol (WAP). Currently, the mobile communication terminal using
the wireless Internet is optimized mainly for purpose of voice
communication and the size of display is small. Thus, only a little
piece of information can be displayed at one time. In addition, it
is inconvenient because a small keypad or a touch screen is only an
input means. Accordingly, information of the wireless Internet
depends on a directory-based menu method.
[0004] Especially, as aforementioned, where contents providers (CP)
embodies directory-based hierarchical menus by considering that the
display or keypad of mobile communication terminal is small, it is
ordinary that the number of selection items included in each of
menus is reduced, so as to get access to a wanted content through
several steps.
[0005] FIG. 1a is a diagram illustrating configuration of
hierarchical menus which are generally adopted in the wireless
Internet.
[0006] As shown in FIG. 1a, menus of the wireless Internet are
formed in such a way that a plurality of menu nodes is arranged in
a hierarchical structure. Herein, as the menu node corresponds to
one location in the entire menu tree, it means a page for selection
of menus in the middle step for going to a content that a user
wants. Each menu node includes lower nodes, wherein the lowest node
includes a menu of contents. In FIG 1a, D1, E1, E2, F1, F2, and GI
mean menus of contents, and A, B, C, D, E, F, and G mean menu
nodes. Moreover, like E2, some menus of comprise variety of menu
nodes for access. A user has to go through A to G menu nodes, in
order to get access to a content that the user wants. Each menu
node has structure, in which menu nodes sequentially separate into
B and C at A, into D and E at B, and F and G at C.
[0007] FIG. 1b is screens of mobile communication terminal showing
procedures of getting access to contents through configuration of
general hierarchical menu in the wireless Internet.
[0008] A user gets access to the wireless Internet through an
Internet access menu, such as for example, `NATE` of SK Telecom,
`Magic-N` of KTF, `Ez-i` of LG Telecom, or the like, by using a
mobile communication terminal. In case that a menu screen by the
first menu node appears as illustrated in IA, the user selects a
directory including contents that the user wants by using a keypad
of the mobile communication terminal. In case that the directory is
selected through the first menu node, a menu screen by a lower menu
node appears. For example, in case that `3.
picture/photo/broadcasting` is selected in IA of the first menu
screen, the lower menu screen appears as shown in IB. In case that
`3. picture friend` is selected, a menu screen by a lower menu node
thereof appears. In case that the current menu node is lowest, each
of contents connected thereto is displayed.
[0009] 1C in FIG 1b is a screen by the lowest menu node. In case
that `2. picture of birds` is selected as shown in IC, a
corresponding content is displayed in a type of characters,
pictures, or moving pictures. Only if the user selects any one
among the displayed characters, pictures, or moving pictures, a
corresponding content is executed on the mobile communication
terminal.
[0010] According to a menu system like above, in order to use
particular contents, the user gets access to contents that the user
wants through procedures of multi-staged menu
selection/confirmation in accordance with a menu system provided as
same every time. Especially, in case that contents that the user
uses frequently are several, the user has to repeat procedures of
menu selection/confirmation by going back to a higher menu.
[0011] In order to delete the repeated procedures like above and
draw a user's convenience, a shortcut method and a link ranking
method are developed and used for a method of constituting menus of
the wireless Internet.
[0012] The shortcut is to additionally provide a route that is
directly connected to a content of a higher menu node, based on the
frequency and the time that the user uses the content. The shortcut
may be automatically generated through a wireless service and may
be manually registered through My page or Shortcut that is
connected in such a way that the user registers contents that the
user frequently uses.
[0013] FIG. 2a is a diagram illustrating configuration of menus by
a shortcut method in the wireless Internet.
[0014] As illustrated in FIG. 2a, structure by a shortcut method of
FIG. 2a is displayed as same as general structure of FIG la. At
this time, a shortcut route is included in several menu nodes. In
FIG. 2a, shortcut routes to E2 and GI are connected at A menu node,
a shortcut route to E2 at B menu node, and a shortcut route to GI
at C menu node. Like A, each menu node may have a plurality of
shortcuts.
[0015] FIG. 2b is screens of mobile communication terminal showing
procedures of getting access to contents through configuration of
shortcut menus in the wireless Internet.
[0016] In case that a user gets access to the wireless Internet by
using the mobile communication terminal, a menu screen by the first
menu node is displayed as shown in 2A. At this time, shortcut
routes are also displayed. That is, shortcuts to `picture of birds`
and `live broadcasting` are included in a menu of `3.
picture/photo/broadcasting`.
[0017] The user selects a shortcut that is directly connected to
contents by using a keypad of mobile communication terminal, or
selects a lower directory including contents that the user wants.
In case that the user selects a lower directory of `3.
picture/photo/broadcasting` in 2A, a screen by a lower menu node is
displayed as shown in 2B. In case that the user selects `picture of
birds`, a shortcut menu, as shown in 2B, a content corresponding
thereto is displayed as shown in 2C. Like above, it is possible for
the user to directly select the content through a shortcut
method.
[0018] The link ranking method is a method that changes orders in
accordance with the number of accesses, the used time, the used
cycle, the used amount, or the like, based on the user's
preferences.
[0019] FIG. 3a is a table showing a utilization ratio of users by
each of contents in the wireless Internet.
[0020] A system computes the utilization ratio by users of each of
contents menus, i.e. D1, E1, E2, F1, F2, and G1. As shown in the
table, a first user has used 10% for F1, 20% for F2 and G1, and 50%
for E2 respectively, without using D1 and E1, a second user has
used 10% for E1, Fl, and G1, 20% for D1 and F2, and 30% for E2
respectively, and a third user has used 10% for G1, 20% for E1, E2,
and F2, and 30% for Fl respectively without using D1. Accordingly,
utilization ratios of each of contents by three users are in order
of E2, F2, F1, G1, E1, and D1.
[0021] Like above, in case that an order is determined based on the
utilization ratio of a user, the wireless Internet organizes menus
in order according to the order thereof.
[0022] FIG. 3b is a diagram illustrating configuration of menus by
a link ranking method in the wireless Internet.
[0023] In order to draw a user's convenience, contents are arranged
in order according to the utilization ratios of users which have
been determined like above. Therefore, contents are arranged in
order of E2, F1, F2, G1, E1, and D1, and routes for getting access
thereto are also rearranged. F for E2, F1, and F2 that are most
used is placed prior to G in the same menu node. In addition, E E1
and E2 that is located in the same menu node, is placed prior to D
for D1. Moreover, higher nodes B and C are also rearranged into C
and B according to the utilization ratios thereof.
[0024] FIG. 3c are screens of mobile communication terminal showing
procedures of getting access to a content through a link ranking
method in the wireless Internet.
[0025] In case that a user gets access to the wireless Internet by
using the mobile communication terminal, a menu screen by the first
menu node is displayed as shown in 3A.
[0026] In the beginning, as shown in 1A in FIG 1b, menu nodes were
in order of`1. mail/photo/chatting`, `2. mybell/music`, `3.
picture/photo/broadcasting`, and `4. game zone`. However, orders
thereof have changed in order of `1. picture/photo/broadcasting`,
`2. game zone`, `3. mail/photo/chatting`, and `4. my bell/music`,
as shown in 3A. At this time, in case that the user selects `1.
picture/photo/broadcasting` including a content that the user
wants, lower menu nodes are also rearranged based on utilization
ratios, as shown in 3B and 3C.
[0027] Accordingly, in case that the link ranking method is used
like above, the possibility goes up that a content mainly used by
users is placed in an upper portion. Thus, a selection becomes more
comfortable because there is no need to scroll down a screen so as
to search for a content that the user wants.
[0028] However, like above, the shortcut method and the link
ranking method have to go through several steps. Contents are
arranged based on the entire users' preferences, not one user's
personal preferences. Therefore, there is no guarantee that
contents that the user wants are always located in an upper
portion. In addition, it might cause inconvenience to a user who
uses contents that other users hardly use. Accordingly, in order to
solve the inconvenience like above, there is provided a method for
manually generating a shortcut that a user wants, however, the user
has tendency to consider it very tiresome because the user has to
designate a shortcut menu one by one.
[0029] Moreover, the shortcut method and the link ranking method
like above are arranged in the same contents, without regard to the
time and location. Therefore, there is required a new method for
facilitating access to particularly demanded contents with respect
to the time or location, for a user who uses different contents in
accordance with the time and location.

current location; searching for a menu page associated with the
accessed time and the current location, by referring to the
database; and transmitting the searched page to the mobile
communication terminal.
BEST MODE FOR CARRYING OUT THE INVENTION
[0042] Hereinafter, the present invention will be described in
detail with reference to the accompanying drawings. It should be
noticed that reference symbols to components of each drawing are
given, so that the same components may have the same symbols
although the components are indicated on respectively different
drawings. In addition, in case that it is determined that concrete
description with respect to related common configuration or
function might make the substance of the present invention
indistinct, the detailed description related thereto is
omitted.
[0043] A system for providing a personalized menu page according to
the present invention obtains a user's location information by
using terminal-based technology such as a GPS or network-based
technology. In case that the user searches for information through
the wireless Internet, the system reorganizes the personalized menu
page into one having configuration of menus, the most suitable for
the relevant time and location, and provides the user with the
reorganized personalized menu page.
[0044] FIG. 4 is a configuration diagram illustrating procedures of
getting access to the wireless Internet through a mobile
communication terminal.
[0045] A system for getting access to the wireless Internet
comprises a mobile communication terminal 410, a mobile
communication network 420, the Internet 440 and a CP server 405,
wherein the mobile communication network comprises a wireless
switching point 422, an Inter-Working Function (hereinafter, `IWF`)
424, a WAP gateway 426, and an Wireless Internet Gateway
(hereinafter, `WIG`) 430.
[0046] The mobile communication terminal 410 enables voice
communication and data communication with a called party through
the mobile communication network 420. The mobile communication
terminal 410 gets access to the Internet 410 via the mobile
communication network 420 by using a browser for Internet access,
such as for example, Wireless Application Protocol (WAP) that is
protocol for getting access to the wireless Internet, HTML-based
Microsoft Internet Explorer (MIE) using HTTP protocol, Handheld
Device Transport Protocol (HDTP), i-Mode of NTT DOKOMO company,
`NATE` of SK Telecommunication, or the like. Among Internet access
protocol used by the mobile communication terminal 410, MIE adopts
m-HTML in which HTML is a little transformed and abbreviated, and
i-Mode adopts a language of compact HTML (c-HTML) that is a subset
of HTML.
[0047] Examples of the mobile communication terminal 410 used in
the present invention include a PDA (Personal Digital Assistant), a
cellular phone, a PCS (Personal Communication Service) phone, a GSM
(Global System for Mobile) phone, a W-CDMA (Wideband Code Division
Multiple Access) phone, a CDMA-2000 phone, a MBS (Mobile Broadband
system) phone, and the like. At this time, the MBS phone is a
mobile phone that will be used in the fourth generation system.
[0048] The wireless switching point 422 receives information such
as the latitude, the longitude, etc from a GPS, and transmits the
received information to the mobile communication terminal 410,
through a system parameter message of forward-link paging channel,
thereby confirming location information of the mobile communication
terminal 410. In addition, the wireless switching point 422
analyzes subscriber information and connects the mobile
communication terminal 410 with IWF 424, so that the same 410 may
get access to the wireless Internet. The wireless switching point
422 may include one piece of CGS (Central Gateway Switch) and a
plurality of wireless switching points getting access thereto.
However, only one piece of switching point is illustrated for brief
indication.
[0049] The IWF 424 provides an interface for exchanging data
between a wireless communication system and a wired communication
system, and servers to convert protocol, signals and data into
types suitable for each network.
[0050] The WAP gateway 426 serves to convert HTTP (HyperText
Transfer Protocol) stack into WAP protocol stack, and inversely
convert WAP protocol stack into HTTP stack. The WAP gateway 426
interoperates with the wired Internet through the WIG 430.
[0051] Furthermore, in configuring routes for accessing wireless
Internet, a proxy server may be adopted instead of the WAP gateway
426. The proxy server serves to separately store information on a
WAP site that a user visits frequently, and in case that the user
gets access to the site, provide the information stored in the
proxy server without going to a server of the WAP site, so as to
avoid a traffic jam that occurs in providing information through
the wireless Internet. The proxy server is used to improve the data
transmission time by decreasing traffics of a network, and may
prevent an unauthorized user from accessing by using a firewall
function.
[0052] The WIG 430 comprises a DNS (Domain Name System) server 432,
a WAP server 434, a database unit 436 and a WEB server 438.
[0053] The DNS server 432 maintains a database with respect to a
domain name on the Internet and an IP address corresponding
thereto. In addition, the DNS server 432 enables the IWF 424 or the
WAP gateway 426 to get access to a CP server 450 through the wired
Internet, by providing an IP address with respect to a domain name
inquired by the IWF 424 or the WAP gateway 426.
[0054] The WAP server 434 organizes a menu for accessing the
wireless Internet and provides the same for the mobile
communication terminal 410 through the WAP gateway 426. Especially,
according to the present invention, in arranging the access menu,
the WAP server 434 automatically generates a personalized menu page
that is optimized according to the location and time, based on
information stored in the database unit 436, and provides each user
with the generated personalized menu page. Rearrangement of the
personalized menu page organized by the WAP server 434 like above
is performed per period (e.g., one month or one week) set by a
manager, or by a user. Therefore, the user can be continuously
provided with the personalized menu page that is optimized for the
user, depending on the user's utilization pattern. "The
personalized menu page" according to the present invention includes
a menu of user interface for selecting predetermined contents, and
means a menu page in which menu configuration is determined by
analyzing the user's utilization patterns by regions or time and
reflecting the analyzed results.
[0055] The personalized menu page like above is a concept
discriminating from "an individually designated menu page" in which
the user directly designates menu configuration of a menu page
provided thereto. The procedure of analysis like above is
unnecessary in a procedure of generating the individually
designated menu page.
[0056] The database unit 436 stores the user's individual
information, i.e. the used time, a used amount, a used period, the
user's menu preference (e.g., in case of selecting the menu, the
user's preference with respect to contents that will be provided),
or a time zone and location pre-set by the user.
[0057] In case that there is a demand from a wired client, the WEB
server 438 provides contents maintained in the WIG 430 with the
wired client through the wired Internet, in accordance with HTTP
protocol.
[0058] The Internet 440 is a communication network providing an
access route, so that the mobile communication terminal 410 may get
access to the CP server 450 through the mobile communication
network 420, so as to receive and transmit data.
[0059] The CP server 450 includes most of contents that are
provided to the mobile communication terminal 410. Moreover,
contents in a certain range may be maintained in the WIG 430, and
the contents are directly transferred to the mobile communication
terminal 410 through the WAP server 434.
[0060] Furthermore, the CP server 450 gets access to the WAP server
434 via the Internet 440 in order to provide contents. At this
time, a part from the CP server 450 may be directly accessed by an
exclusive line.
[0061] FIG. 5 is a block diagram illustrating configuration of a
system providing a personalized menu page according to the
embodiment of the present invention. The database unit 436 of FIG.
5 illustrates one example of data structure that may be adopted for
arranging and providing the personalized menu page.
[0062] A system for providing a WAP page comprises a publication
& request processing unit 502, a personalized menu page unit
504, a management program unit 506, a personalization
recommendation engine unit 508 and the database unit 436, wherein
the database unit 436 may comprise a WAP site & contents
information DB 510, a meta data DB 512, a terminal profile
information DB 514, a customer profile information DB 516, a
customer utilization information DB 518, a personalization
recommendation information DB 520 and a location information/time
information DB 522.
[0063] The publication & request processing unit 502 serves to
receive a request for processing of a menu page that includes a
menu for selecting a content, from a user through the mobile
communication network, and to produce a menu page of which menu
configuration is processed for characteristics of the user's mobile
communication terminal 410 and the user's request, so as to provide
the same with the user. In the present specification, it is called
as `publication` to produce the menu page like using a markup
language or the like. In addition, the publication and request
processing unit 502 serves to generate and store log information
record that is necessary for generating and analyzing the user's
individual preferences.
[0064] The personalized menu page unit 504 serves to form and
provide a menu page in such a way that the user's menu page
utilization pattern, characteristics of the mobile communication
terminal 410, recommendation information and the like are combined
into dynamically changed page structure by using data of the
database unit 436, in accordance with a request of the publication
& request processing unit 502. Namely, the personalized menu
page unit 504 serves to provide the dynamic personalized menu page
based on the user's individual utilization particulars and
characteristics thereof. In addition, in case that there is a
user's request, the personalized menu page unit 504 serves to
generate and provide the personalized menu page of which menu
configuration is suitable for the user's location, by using the
location information stored in the database unit 436, based on the
user location information obtained from the mobile communication
terminal 410.
[0065] The management program unit 506 forms basic structure of the
WAP site to be searched by the user, and manages link information
and page information with respect to the internal WAP site, screen
configuration and design, and link information with contents
providers (CP). In addition, the management program unit 506 is
configured to set up options with respect to a personalized
adaptation method, based on generation of reports with respect to
the user's search record information, characteristics of the mobile
communication terminal 410 such as the size of display, kinds of
the terminal, the wireless Internet access speed and the like, and
character of information.
[0066] The personalization recommendation engine unit 508 serves to
generate a recommendation link by analyzing the user's utilization
pattern and disposition through adaptation of some analysis
algorithm and computing recommendation information for providing
the user with correct information.
[0067] Moreover, in case that the user accesses through the
wireless Internet, the personalization recommendation engine unit
508 serves to control the publication & request processing unit
502 to determine whether the accessed time is designated or whether
the accessed location is designated, and in case that it is
determined that the accessed time or location is designated, to
provide the personalized menu page, and otherwise, to provide a
general menu page.
[0068] The WAP site & content information DB 510 stores an
address of the WAP page which is necessary for building the WAP
site, structure of the WAP site which is formed of a DAG(Directed
Acyclic Graph), and a name of the WAP page. WAP site information is
dispersed not only to pages that are located in the unitary server,
but also to a plurality of servers, thereby being connected to the
contents WAP site of contents providers (CP). The WAP site &
contents information DB 510 stores link information and WAP pages
that are dispersed to severs like above, and information of other
objects that exist within the WAP page.
[0069] The meta data DB 512 stores explanation with respect to the
WAP page, classification information, the generated date, the
corrected date, and the like, so as to facilitate management,
search and analysis with respect to the WAP page.
[0070] The terminal profile information DB 514 stores browser
information, the size of display, resolution, backup software
environments, etc with respect to each mobile communication
terminal 410 held by the user, and in case that personalization
information is provided, serves to provide information suitable for
the corresponding mobile communication terminal 410 by using the
provided information.
[0071] The customer profile information DB 516 stores the user's
subscription information and setup information, and the user's
personal information such as a sex, an age, an occupation, and the
like, by using a unique number that can recognize the user, i.e. a
telephone number of the mobile communication terminal 410, the user
ID or a serial number of the mobile communication terminal 410. At
this time, terminal and customer profile information may be
received through a rule such as CC/PP (Composite Capability and
Preference Profile) or UAProf (User Agent Profile).
[0072] The customer utilization record DB 518 serves to analyze WAP
page utilization record searched through the mobile communication
terminal 410 of the user and store the analyzed record in a type
suitable for the personalization.
[0073] The personalization recommendation information DB 520 serves
to store personalization information generated through the
personalization recommendation engine unit 508, and provide the
personalization information to the personalized menu page unit
504.
[0074] The location information/time information DB 522 manages LID
(Location ID) for indicating location information and TID (Time ID)
for indicating time information. LID and TID are divided into a
system designated value and a user designated value. At this time,
the system designated LID is a value that the system has divided
the whole country into the meaningful minimum unit, and the user
designated LID is a value that each user has stored a region that
is determined to be meaningful to the user. In addition, the system
designated TID is a value that the system has divided 24 hours into
the meaningful minimum unit, and the user designated TID is a time
value that the user has set up for management.
[0075] FIG. 6a is a diagram illustrating menu configuration by a
recommendation link method generated in the personalization
recommendation engine unit 508.
[0076] Generation of recommendation link may be performed in a menu
configuration method in which users analyze the number of
synchronous events of menu selections to be provided with
predetermined contents, or find other menu used mainly by other
homogeneous users who have selected a corresponding menu, analyze
the menu, and give a priority thereto.
[0077] The personalization recommendation engine unit 508 analyzes
the user's preferences or utilization pattern by using variety of
algorithm such as information filtering algorithm like
collaborative filtering or rules-based filtering based on
similarity between page links, similarity between users, etc,
reasoning algorithm like case-based reasoning, rules-based
reasoning, etc, data mining algorithm like association rule,
clustering, etc, and the like.
[0078] As illustrated in FIG. 6a, the recommendation link appears
in such a way that a new link is connected between D and F, a link
to F appears additionally when the menu screen of D is output, and
on the contrary, a link to D appears when the menu screen of F is
output. At this time, there is no direct link between D and F.
[0079] It is not that recommendation links should be
bi-directionally formed between two menu nodes like D and F. As
shown in relation between E and G, a unidirectional link may be
formed. In this case, a unidirectional link is formed and developed
only from E to G. Therefore, although a link to G is added to the
menu screen when the menu screen of E is output, a link to E is not
output when the menu screen of G is output.
[0080] FIG. 6b is screens of the mobile communication terminal for
showing procedures of getting access to contents by the
recommendation link method in the wireless Internet.
[0081] In case that the user accesses the wireless Internet by
using the mobile communication terminal, a menu screen by the first
menu node is displayed as illustrated in 6A, the user selects a
directory including a content the user wants, by using a key pad of
the mobile communication terminal. For example, in case that the
user selects `4. game zone` in the menu screen 6A, a lower menu
screen of `4. game zone` is displayed as illustrated in 6B. In
addition, although they are not lower menus of `4. game zone`,
`game news` and `game community` are displayed in the lower part of
the menu screen, wherein the both are recommendation menus
associated with `4. game zone`. Therefore, it is possible for the
user to get access to a corresponding content by using the
recommendation menus `game news` or `game community`.
[0082] It is possible to provide the associated recommendation
menus like 6B in FIG. 6b. Moreover, it is also possible to provide
menus that users often use, as recommendation menus by analyzing
the users who have used `4. game zone` frequently.
[0083] Like above, the personalization recommendation engine unit
508 generates the recommendation link method, and a menu page is
arranged thereby. At this time, it is possible to arrange menus by
using only recommendation link method that has analyzed other
users. In addition, it is also possible to arrange a menu page
including a menu by the recommendation link method, a preference
menu that a user accesses often personally, and an individual
shortcut menu that is pre-set by the user.
[0084] FIG. 7 is a table for computing frequency of selection of
each menu of menu page per time and per location according to one
embodiment of the present invention.
[0085] In case that a user's ID is UID and menu information
selected by the user is PID, together with the aforementioned
location identifier LID and time identifier TID, the system for
providing a personalized menu page according to the present
invention accumulates utilization preferences of PID, by TID, UID,
and LID, wherein the PID was used by users in the past.
[0086] In the table of FIG. 7, each page is divided into pages of
T1, T2, T3 . . . by TID. At this time, cross rows of the page by
each TID are classified by LID and down lines are classified by
PID.
[0087] In the certain time T1, a user has used P1 once, P2 twice,
P3 four times and P4 zero, at the location of L1. Utilization
ratios with respect thereto are respectively 10%, 30%, 60% and 0%,
as shown in the table below.
[0088] The current state in which each menu has been used at the
location of L2, P1 is once, P2 is zero, P3 is five times, and P4 is
four time. Thus, each utilization ratio thereof is 10%, 0%, 50% and
40%. Like above, the number of utilization or utilization ratios is
computed with respect to each of LID.
[0089] Furthermore, the present invention enables the user to
designate the meaningful location and time zone. For example, in
case that the user designates L2 as a particular location and gets
access to the wireless Internet at the time T1 at the designated
location L2, personalized menu pages are arranged in order of P3,
P4, P1, and P2 which the user mainly uses. At this time, the
meaningful location that the user can designate is not limited to
one. That is, the user designates L2 as a residence place and L3 as
a working place, and the user is at the residence place. In this
case, it is possible to provide a personalized menu page according
to L2. In addition, in case that the user is at the working place,
it is possible to provide a personalized menu page according to L3.
In case that the user is at a place besides the designated places,
a general menu page according to a method for arranging
recommendation links generated by the personalization
recommendation engine unit, may be provided.
[0090] The term of the general menu page in the present
specification means a menu page having common menu configuration
with respect to a plurality of users or the entire users, which is
unlike the personalized menu page that is generated by considering
a user's disposition of menu selection at a predetermined time zone
or location by users.
[0091] Furthermore, besides the method that the user designates a
location, it is possible to provide the personalized menu page in
which menus are arranged based on utilization ratios at the
location where the user has accessed, and to provide the general
menu page at the location where the user has not accessed
before.
[0092] At this time, configuration of menu nodes according to the
present invention is similar to FIG. 3b. However, the structure of
menu nodes does not consist of one structure as shown in 3b, but
consists of several menu nodes according to time and location.
Therefore, there are several menu node structures according to the
time and location, with respect to one person. For example, there
may be comprised menu nodes of `(the number of designated time x
the number of designated locations)+the number of designated
time+the number of designated locations+1`. At this time, `the
number of designated time.times.the number of designated locations`
is the number of personalized menu pages that are provided where
the user is at the designated location and at the designated time.
In addition, `the number of designated time` is the number of
personalized menu pages that are provided where the time is
designated, however, the location is undesignated. `The number of
designated locations` is the number of personalized menu pages that
are provided where the user is at the designated location at the
undesignated time. Finally, `1` means a menu page that is provided
by the recommendation link method. In the meantime, the menu page
according to each time and location is not pre-generated and
stored, but generated dynamically in the personalized menu page
unit 504 by reflecting the user's access states.
[0093] FIG. 8a is an example of screens for explaining a method of
finding a restaurant using the mobile communication terminal
according to the conventional configuration of menu pages.
[0094] In case that a user wants to find a western-styled
restaurant in the region of Kangnam and accesses the wireless
Internet through the mobile communication terminal 410, a menu
screen as shown in 8A of FIG. 8 is displayed, and the user gets
into a search window for traffic/location information of the
corresponding region, through `4. traffic/location` among menus. In
case that the user enters the menu of `find restaurants` in order
to find out the restaurant at 8B of FIG. 8, the menu screen for
selecting the relevant region is displayed as shown in 8C of FIG.
8. The user first selects `Seoul` at cities and selects
`Kangnam-gu` at detailed regions through the step of 8D of FIG. 8.
In case that the input is completed, the user selects a kind of
restaurants through the screen of 8E of FIG. 8. In case that the
user selects `2. western-styled` restaurants, western-styled
restaurants are displayed as shown in 8F of FIG. 8. In the end, the
user can obtain contents information with respect to a
corresponding restaurant by selecting one.
[0095] However, configuration of menu pages according to the
present invention is simplified as illustrated in FIG. 8b.
[0096] In case that a user gets access to the wireless Internet at
the pre-designated location, `Kangnam-gu`, configuration of menus
is completed as shown in 8G of FIG. 8. The configuration of menus
is set to give a priority to a menu that the user mainly uses at
the particular location LID at the particular time TID.
[0097] The method for providing a menu page according to the
present invention considers the user's disposition of selecting a
predetermined menu at the designated location, and based thereon,
generates a personalized menu page.
[0098] The disposition may be measured by user preferences. The
user preferences may be computed by reflecting frequency that the
user has selected a menu included in the personalized menu page,
the service using time where the user is provided with a
predetermined service (e.g., a game service, a music service, a
search service, etc) by selecting the menu, the service charges to
be paid by the user where the user is provided with the
service.
[0099] According to embodiments, user preferences may be computed
by reflecting any one of the frequency, the service using time, and
the service charges. In the mean time, user preferences may be
computed by considering the frequency and the like in
combination.
[0100] According to one embodiment of the present invention, the
personalized menu page unit 504 respectively computes the frequency
with respect to the predetermined menu at the designated location
during a certain period, the service using time, or the service
charges, and computes user preferences with respect to the menu at
the designated location, by giving weight to the frequency and the
like.
[0101] Furthermore, according to another embodiment of the present
invention, the weight may be for computing the relative frequency,
the relative service using time, the relative service charges, or
the like, in the relation between a predetermined menu and other
menu. For example, the predetermined menu page provides three menus
such as a first menu, a second menu, and a third menu and the user
selects the first menu three times, the second menu twice, and the
third menu five times. In this case, the relative frequency with
respect to each of menus is 3/(3+2+5)=0.3 for the first menu,
2/(3+2+5)=0.2 for the second menu and 5/(3+2+5)=0.5 for the third
menu.
[0102] Furthermore, according to another embodiment of the present
invention, the weight may be for adjusting a unit difference
between the frequency, the service using time, and the service
charges.
[0103] Furthermore, according to another embodiment of the present
invention, the weight may be for further reflecting any one of
frequency, the service using time, and the service charges, in user
preferences.
[0104] In the meantime, according to another embodiment of the
present invention, the personalized menu page unit 504 may compute
user preferences by using user preferences by unit periods in order
to reflect the latest disposition that the user selects menus.
Hereinafter, this will be in detail described.
[0105] First, the personalized menu page unit 504 computes user
preferences by unit periods for each of menus. "User preference by
unit periods" means user preferences that are computed by using
frequency, service using time or service charges during the unit
period. In case that the unit period is set by one day, the
personalized menu page 504 computes the user preference every day.
Therefore, today's user preferences by unit periods may be computed
by respectively reflecting the number that the user has selected a
relevant menu at the designated location during today, one day, the
time that the user has used a service provided by selecting the
menu, and charges that the user has to pay so as to use the
service.
[0106] Furthermore, the personalized menu page unit 504 also
computes user preferences per unit period, by using user
preferences by unit periods that are newly computed per unit
period. In case that the unit period is set by one day as
aforementioned, and today is 30th of December, it is assumed that
daily-computed user preferences by unit periods with respect to the
predetermined menu are respectively 0.8 on 28th of December, 0.7 on
29th of December, and 0.5 on 30th of December.
[0107] At this time, in case that user preferences of 29th of
December which had been computed with respect to the menu, were
0.8, the personalized menu page unit 504 may compute "user
preferences of 30th of December" by using "that of 29th of
December" and "user preferences by unit periods computed with
respect to 30th of December". At this time, the personalized menu
page unit 504 may enable the user's latest disposition of menu
selection to be further reflected, by giving more weight to the
user preferences by unit periods of 30th of December.
[0108] For example, in case that user preferences which are
computed currently are called as "current user preferences" and
user preferences which had been computed just before are called as
"former user preferences", wherein current user preferences may be
computed as below.
[0109] Current user preferences=(former user
preferences.times.a)+(user preferences by the latest unit
period.times.b)
[0110] Current user preferences computed as above is used for
computing the following current user preferences, as former user
preferences after the unit period passes. The personalized menu
page unit 504 determines current user preferences as the
aforementioned user preferences, wherein the current user
preferences were computed in the last on the basis of the time of
providing the user with a menu page.
[0111] The a and b are weighted values, and the personalized menu
page unit 504 enables the latest disposition of selection of menus
to be further reflected in user preferences by selecting a value of
b to be larger in comparison with a.
[0112] In addition, the personalized menu page unit 504 computes
user preferences by menus respectively, and gives a priority to
each menu by reflecting user preferences computed like above. For
example, a higher priority is given to a menu with higher user
preferences.
[0113] Furthermore, the aforementioned embodiment has described
where user preferences of each menu are computed at the designated
location. However, according to another embodiment of the present
invention, the personalized menu page unit 504 may compute user
preferences of each menu at the designated location and time.
[0114] Furthermore, the personalized menu page unit 504 may arrange
menus of the personalized menu page that are provided for the user,
based on the priority.
[0115] For example, the personalized menu page unit 504 may enable
a menu with a higher priority to be placed in the upper portion of
the same menu page. In case that the priority order of
"male/photo/chatting" menu is prior to that of "my bell/ music"
menu, the personalized menu page unit 504 may enable the
"mail/photo/chatting" menu to be placed in the upper portion in
comparison with the "mybell/music" menu, as shown in 6A of FIG.
6.
[0116] Furthermore, the personalized menu page unit 504 may
generate the personalized menu page, so that a menu with a higher
priority may be located in a menu page with a lower depth of the
menu. The personalized menu page may have at least one sub menu
page with at least tow depths. For example, 6B of FIG. 6 is one of
sub menu pages of 6A, and the depth of 6B is deeper than that of 6A
by one. The personalized menu page unit 504 enables a user to get
access to the menu easily, by placing the menu with a higher
priority at a menu page with a lower depth.
[0117] Furthermore, with respect to a menu with a higher priority,
the personalized menu page unit 504 may add a shortcut thereto, to
a menu page with a depth lower than the existing location of the
menu. For example, in case that the menu is located at a sub menu
page with three depths, the personalized menu page unit 504 may add
a short cut with respect to the menu, to a sub menu page with one
depth. Accordingly, the user may select a shortcut displayed on the
sub menu page with one depth, or the menu displayed on the sub menu
page with three depths, thereby asking providing of content
corresponding to the menu.
[0118] Furthermore, the personalized menu page unit 504 may
indicate a menu with higher priority, in a different type from a
menu with a lower priority. For example, the personalized menu page
unit 504 may generate the personalized menu page, so that the menu
with a high priority may be indicated in red and the menu with a
low priority in black, at the same personalized menu page.
[0119] In case that the user selects one's wanted menu, i.e. "2.
find restaurants", the system for providing a personalized menu
page displays a screen for selecting kinds of restaurants in the
corresponding location, as shown in 8H of FIG. 8, so that the user
may select one. The screen for selecting kinds of restaurants is
also displayed in accordance with the ratio that the user has
selected menus.
[0120] In case that the user selects one's wanted restaurant, lists
of restaurants in the corresponding region are displayed according
to ratios of selection of menus that the user has selected. The
user selects a restaurant and searches for contents
information.
[0121] Like above, according to the present invention, it is
possible to reduce steps in searching for information through the
wireless Internet using the mobile communication terminal. In
addition, it is also possible to facilitate a selection of contents
because a menu that used to be used most by the user's past
utilization information is displayed in the upper portion of the
personalized menu page.
[0122] Furthermore, the utilization ratio of menu according to the
present invention may depend only on the user's individual past
utilization information. However, it is also possible to provide a
general menu page in a type of recommendation service at the
location where the user has not set up, by using past utilization
information that a group of users who have a similar disposition to
the user, or the entire users have used at the particular location
at the particular time zone.
[0123] FIG. 9 is a flowchart for explaining procedures of providing
a personalized menu page according to the present invention.
[0124] A user gets access to the wireless Internet through the
mobile communication network 420, for the purpose of obtaining
information via the mobile communication terminal 410 (S902). In
case that the user gets access to the mobile communication network
420, location information is confirmed by obtaining information
such as the latitude, the longitude, etc through a GPS, and time
information is grasped through the wireless switching point 422
(S904).
[0125] In case that time information is confirmed, it is determined
whether the time information corresponds to the time zone
pre-designated by the user (S906). After confirmation of the time
zone, the corresponding time zone is selected and it is determined
whether the user's location corresponds to the pre-designated
location (S908).
[0126] In case that the user searches for information at the
designated location at the designated time, a personalized menu
page is generated (S910), wherein the personalized menu page has
configuration of menus based on frequency of selection of menus
that the user has selected in order to be provided with
predetermined contents at the relevant location at the relevant
time. In case that the user asks a search of information at the
designated time, however, at a place where the user has
undesignated, the personalized menu page is generated by reflecting
frequency of selection of menus at the relevant time without regard
to the location (S912). The process of generating the personalized
menu page by reflecting frequency of selection of menus and
determining configuration of menus of the personalized menu page is
as same as aforementioned.
[0127] At the results of steps S906 and S908, in case that it is
determined that the user has asked a search of information at the
designated location at the undesignated time (S914), the
personalized menu page is generated by reflecting frequency of
selection of menus at the relevant location without regard to the
time (S916).
[0128] The personalized menu page generated in the steps S910, S912
and S916 is transmitted to the user's mobile communication terminal
410, so as to facilitate the user's search of information (S920).
Accordingly, the user may be provided with the personalized menu
page that is optimized for oneself, by times or by locations.
[0129] However, at the results of steps S906 and S914, in case that
it is determined that neither time nor location is designated, the
general menu page such as a menu page generated by a recommendation
link, an individually-designated menu page, or the like, is
provided to the user's mobile communication terminal 410
(S918).
[0130] In case that the user selects a menu included in the
personalized menu page or the general menu page through the
wireless Internet and is provided with contents corresponding to
the selected menu, the system stores the user's log records and
uses the same as data for computing frequency of selection of menus
in case that there is the next request for access (S922).
[0131] The system computes utilization ratios with respect to
individuals and the entire users through the above user utilization
log and uses location information and time information, so as to
organize configuration of the personalized menu page.
[0132] Furthermore, in the embodiment of the present invention, in
case that the personalized menu page is organized only by using
location information where the user is placed, without regard to
the time, it is possible to omit steps S906 to S912.
[0133] Furthermore, although an example of providing a menu page
such as the personalized menu page or the like to the WAP page is
described in the aforementioned embodiment, this is only for an
example. Thus, the menu page may be embodied as the WAP page by
using a markup language. The scope of the present invention is not
limited or restricted thereby.
[0134] Although the present invention has been described in
connection with the embodiment of the present invention illustrated
in the accompanying drawings, it is not limited thereto since it
will be apparent to those skilled in the art that various
substitutions, modifications and changes may be made thereto
without departing from the scope and spirit of the invention.
Therefore, it is intended that the scope of the invention be
defined by the claims appended thereto and their equivalents.
INDUSTRIAL APPLICABILITY
[0135] As aforementioned, according to the present invention, it is
possible to provide a personalized menu page by users, wherein the
personalized menu page has enhanced accessibility to a menu that a
user mainly uses personally according to time and location, in
comparison with other menus. In addition, in the user's position,
it is possible to find one's wanted information faster.
